In the highway asphalt concrete road surface, both SMA and Super pave technology need high requirement of the shape and rank of aggregate. Especially to the content of needle plate type in the basalt, the former impact crusher processing chart cannot meet the requirement any longer. Therefore, our company puts up the newest crushing and screening processing chart-VI series of Vertical Shaft Impact Crusher to meet the need. The high-quality aggregate produced by this production line is widely used in road surface of many highways.

Basalt Aggregate for Express Highway Processing Chart:

1. GZD Series Vibrating Feeder
2. PE/PEX Series Jaw Crusher
3. PF Series Hard Rock Impact Crusher or Cone Crusher
4. YZS Series Vibrating Screen
5. VSI Series Vertical Shaft Impact Crushers

The features of the processing:

1. The quality of the product is very high. Content of needle plate type is no more than 5%. A diabase in Africa, once adopted Jaw Crusher and Impact Crusher. But content of needle plate type is more than 10%, resulting the bad sell of its product. After using VSI Series Vertical Shaft Impact Crushers, the content of needle plate type in the product is reduced to 4.7%.

2. The production improves 50% compared with utilizing Impact Crusher as the final processing of crushing.

3. Because we utilize Impact Crusher as the secondary crusher, and Vertical Shaft Impact Crusher consumes little metal, the consumption of wear-parts is reduced greatly in the whole process.
